Spring Cloud Configuration Server - Spring Cloud HashiCorp Vault

Spring Cloud Configuration Server is able to use Vault to locate properties and settings. To learn more about configuration security, please review this guide.

The following settings and properties are available from the CAS configuration catalog:

_{The configuration settings listed below are tagged as Required in the CAS configuration metadata. This flag indicates that the presence of the setting may be needed to activate or affect the behavior of the CAS feature and generally should be reviewed, possibly owned and adjusted. If the setting is assigned a default value, you do not need to strictly put the setting in your copy of the configuration, but should review it nonetheless to make sure it matches your deployment expectations.}

_{The configuration settings listed below are tagged as Optional in the CAS configuration metadata. This
flag indicates that the presence of the setting
is not immediately necessary in the end-user CAS configuration, because a default value is assigned or
the activation of the feature is not conditionally controlled by the setting value. In other words, you should only include this field in your
configuration if you need to modify the default value or if you need to turn on the feature controlled by the setting.}

_{The configuration settings listed below are tagged as Third Party in the CAS configuration metadata. This flag indicates that the configuration setting is not controlled, owned or managed by the CAS ecosystem, and affects functionality that is offered by a third-party library, such as Spring Boot or Spring Cloud to CAS. For additional info, you might have to visit the third-party source to find more details.}

Configuration Metadata

The collection of configuration properties listed in this section are automatically generated from the CAS source and components that contain the actual field definitions, types, descriptions, modules, etc. This metadata may not always be 100% accurate, or could be lacking details and sufficient explanations.

Be Selective

This section is meant as a guide only. Do NOT copy/paste the entire collection of settings into your CAS configuration; rather pick only the properties that you need. Do NOT enable settings unless you are certain of their purpose and do NOT copy settings into your configuration only to keep them as reference. All these ideas lead to upgrade headaches, maintenance nightmares and premature aging.

YAGNI

Note that for nearly ALL use cases, declaring and configuring properties listed here is sufficient. You should NOT have to explicitly massage a CAS XML/Java/etc configuration file to design an authentication handler, create attribute release policies, etc. CAS at runtime will auto-configure all required changes for you. If you are unsure about the meaning of a given CAS setting, do NOT turn it on without hesitation. Review the codebase or better yet, ask questions to clarify the intended behavior.

Naming Convention

Property names can be specified in very relaxed terms. For instance cas.someProperty, cas.some-property, cas.some_property are all valid names. While all forms are accepted by CAS, there are certain components (in CAS and other frameworks used) whose activation at runtime is conditional on a property value, where this property is required to have been specified in CAS configuration using kebab case. This is both true for properties that are owned by CAS as well as those that might be presented to the system via an external library or framework such as Spring Boot, etc.

Note

When possible, properties should be stored in lower-case kebab format, such as cas.property-name=value. The only possible exception to this rule is when naming actuator endpoints; The name of the actuator endpoints (i.e. ssoSessions) MUST remain in camelCase mode.

Settings and properties that are controlled by the CAS platform directly always begin with the prefix cas. All other settings are controlled and provided to CAS via other underlying frameworks and may have their own schemas and syntax. BE CAREFUL with the distinction. Unrecognized properties are rejected by CAS and/or frameworks upon which CAS depends. This means if you somehow misspell a property definition or fail to adhere to the dot-notation syntax and such, your setting is entirely refused by CAS and likely the feature it controls will never be activated in the way you intend.

Validation

Configuration properties are automatically validated on CAS startup to report issues with configuration binding, specially if defined CAS settings cannot be recognized or validated by the configuration schema. The validation process is on by default and can be skipped on startup using a special system property SKIP_CONFIG_VALIDATION that should be set to true. Additional validation processes are also handled via Configuration Metadata and property migrations applied automatically on startup by Spring Boot and family.

Indexed Settings

CAS settings able to accept multiple values are typically documented with an index, such as cas.some.setting[0]=value. The index [0] is meant to be incremented by the adopter to allow for distinct multiple configuration blocks.

Usage

The configuration modules provided here may also be used verbatim inside a CAS server overlay and do not exclusively belong to a Spring Cloud Configuration server. While this module is primarily useful when inside the Spring Cloud Configuration server, it nonetheless may also be used inside a CAS server overlay directly to fetch settings from a source.

Actuator Endpoints

The following endpoints are provided by CAS:

The following settings and properties are available from the CAS configuration catalog:


`cas.monitor.endpoints.jdbc.password-encoder.encoding-algorithm=` The encoding algorithm to use such as `MD5`. Relevant when the type used is `DEFAULT` or `GLIBC_CRYPT`. When used with `PasswordEncoderTypes#PBKDF2`, it should be one of `PBKDF2WithHmacSHA1`, `PBKDF2WithHmacSHA256` or `PBKDF2WithHmacSHA512`. `org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.`
`cas.monitor.endpoints.jdbc.password-encoder.type=NONE` Define the password encoder type to use. Type may be specified as blank or `NONE` to disable password encoding. It may also refer to a fully-qualified class name that implements the Spring Security's `PasswordEncoder` interface if you wish you define your own encoder. The following types may be used: `NONE`: No password encoding (i.e. plain-text) takes place. `DEFAULT`: Use the `DefaultPasswordEncoder` of CAS. For message-digest algorithms via `character-encoding` and `encoding-algorithm`. `BCRYPT`: Use the `BCryptPasswordEncoder` based on the strength provided and an optional secret. `SCRYPT`: Use the `SCryptPasswordEncoder`. `PBKDF2`: Use the `Pbkdf2PasswordEncoder` based on the strength provided and an optional secret. `STANDARD`: Use the `StandardPasswordEncoder` based on the secret provided. `SSHA`: Use the `LdapShaPasswordEncoder` supports Ldap SHA and SSHA (salted-SHA). The values are base-64 encoded and have the label {SHA</code> or {SSHA</code> prepended to the encoded hash. `GLIBC_CRYPT`: Use the `GlibcCryptPasswordEncoder` based on the `encoding-algorithm`, strength provided and an optional secret. `org.example.MyEncoder`: An implementation of `PasswordEncoder` of your own choosing. `file:///path/to/script.groovy`: Path to a Groovy script charged with handling password encoding operations. `org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.`

`cas.monitor.endpoints.jdbc.ddl-auto=update` Hibernate feature to automatically validate and exports DDL to the schema. By default, creates and drops the schema automatically when a session is starts and ends. Setting the value to `validate` or `none` may be more desirable for production, but any of the following options can be used: `validate`: Validate the schema, but make no changes to the database. `update`: Update the schema. `create`: Create the schema, destroying previous data. `create-drop`: Drop the schema at the end of the session. `none`: Do nothing. Note that during a version migration where any schema has changed `create-drop` will result in the loss of all data as soon as CAS is started. For transient data like tickets this is probably not an issue, but in cases like the audit table important data could be lost. Using `update`, while safe for data, is confirmed to result in invalid database state. `validate` or `none` settings are likely the only safe options for production use. For more info, see this. `org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.jdbc.default-catalog=` Qualifies unqualified table names with the given catalog in generated SQL. `org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.`

`cas.monitor.endpoints.jdbc.fail-fast-timeout=1` Set the pool initialization failure timeout. Any value greater than zero will be treated as a timeout for pool initialization. The calling thread will be blocked from continuing until a successful connection to the database, or until the timeout is reached. If the timeout is reached, then a `PoolInitializationException` will be thrown. A value of zero will not prevent the pool from starting in the case that a connection cannot be obtained. However, upon start the pool will attempt to obtain a connection and validate that the `connectionTestQuery` and `connectionInitSql` are valid. If those validations fail, an exception will be thrown. If a connection cannot be obtained, the validation is skipped and the the pool will start and continue to try to obtain connections in the background. This can mean that callers to `DataSource#getConnection()` may encounter exceptions. A value less than zero will not bypass any connection attempt and validation during startup, and therefore the pool will start immediately. The pool will continue to try to obtain connections in the background. This can mean that callers to `DataSource#getConnection()` may encounter exceptions. Note that if this timeout value is greater than or equal to zero (0), and therefore an initial connection validation is performed, this timeout does not override the `connectionTimeout` or `validationTimeout`; they will be honored before this timeout is applied. The default value is one millisecond. `org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.`

`cas.jdbc.case-insensitive=false` When choosing physical table names, determine whether names should be considered case-insensitive.
`cas.jdbc.gen-ddl=true` Whether to generate DDL after the EntityManagerFactory has been initialized creating/updating all relevant tables.
`cas.jdbc.physical-table-names=` Indicate a physical table name to be used by the hibernate naming strategy in case table names need to be customized for the specific type of database. The key here indicates the CAS-provided table name and the value is the translate physical name for the database. If a match is not found for the CAS-provided table name, then that name will be used by default.
`cas.jdbc.show-sql=false` Whether SQL queries should be displayed in the console/logs.


`cas.monitor.endpoints.jdbc.password-encoder.encoding-algorithm=` The encoding algorithm to use such as `MD5`. Relevant when the type used is `DEFAULT` or `GLIBC_CRYPT`.

`cas.monitor.endpoints.jdbc.password-encoder.type=NONE` Define the password encoder type to use. Type may be specified as blank or `NONE` to disable password encoding. It may also refer to a fully-qualified class name that implements the Spring Security's `PasswordEncoder` interface if you wish you define your own encoder. The following types may be used: `NONE`: No password encoding (i.e. plain-text) takes place. `DEFAULT`: Use the `DefaultPasswordEncoder` of CAS. For message-digest algorithms via `character-encoding` and `encoding-algorithm`. `BCRYPT`: Use the `BCryptPasswordEncoder` based on the strength provided and an optional secret. `SCRYPT`: Use the `SCryptPasswordEncoder`. `PBKDF2`: Use the `Pbkdf2PasswordEncoder` based on the strength provided and an optional secret. `STANDARD`: Use the `StandardPasswordEncoder` based on the secret provided. `SSHA`: Use the `LdapShaPasswordEncoder` supports Ldap SHA and SSHA (salted-SHA).

`cas.monitor.endpoints.jdbc.password-encoder.strength=16` Strength or number of iterations to use for password hashing. Usually relevant when dealing with `PasswordEncoderTypes#BCRYPT`, `PasswordEncoderTypes#PBKDF2` or `PasswordEncoderTypes#GLIBC_CRYPT`. When used by `PasswordEncoderTypes#ARGON2` or `PasswordEncoderTypes#PBKDF2`, it indicates the salt strength. `org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.`

If you need to design your own password encoding scheme where the type is specified as a fully qualified Java class name, the structure of the class would be similar to the following:

package org.example.cas;

import org.springframework.security.crypto.codec.*;
import org.springframework.security.crypto.password.*;

public class MyEncoder extends AbstractPasswordEncoder {
    @Override
    protected byte[] encode(CharSequence rawPassword, byte[] salt) {
        return ...
    }
}

If you need to design your own password encoding scheme where the type is specified as a path to a Groovy script, the structure of the script would be similar to the following:

import java.util.*

byte[] run(final Object... args) {
    def rawPassword = args[0]
    def generatedSalt = args[1]
    def logger = args[2]
    def casApplicationContext = args[3]

    logger.debug("Encoding password...")
    return ...
}

Boolean matches(final Object... args) {
    def rawPassword = args[0]
    def encodedPassword = args[1]
    def logger = args[2]
    def casApplicationContext = args[3]

   logger.debug("Does match or not ?");
   return ...

The following settings and properties are available from the CAS configuration catalog:


`cas.monitor.endpoints.ldap.base-dn=` Base DN to use. There may be scenarios where different parts of a single LDAP tree could be considered as base-dns. Rather than duplicating the LDAP configuration block for each individual base-dn, each entry can be specified and joined together using a special delimiter character. The user DN is retrieved using the combination of all base-dn and DN resolvers in the order defined. DN resolution should fail if multiple DNs are found. Otherwise the first DN found is returned. Usual syntax is: `subtreeA,dc=example,dc=net\|subtreeC,dc=example,dc=net`. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.bind-credential=` The bind credential to use when connecting to LDAP. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`

SASL mechanism provided - Use the given SASL mechanism to bind when initializing connections. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.ldap-url=` The LDAP url to the server. More than one may be specified, separated by space and/or comma. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.search-filter=` User filter to use for searching. Syntax is `cn={user}` or `cn={0}`. You may also provide an external groovy script in the syntax of `file:/path/to/GroovyScript.groovy` to fully build the final filter template dynamically. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.type=AUTHENTICATED` The authentication type. `AD` - Users authenticate with `sAMAccountName`. `AUTHENTICATED` - Manager bind/search type of authentication. If { principalAttributePassword</code> is empty then a user simple bind is done to validate credentials. Otherwise the given attribute is compared with the given `principalAttributePassword` using the `SHA` encrypted value of it. `ANONYMOUS`: Similar semantics as `AUTHENTICATED` except no `bindDn` and `bindCredential` may be specified to initialize the connection. If `principalAttributePassword` is empty then a user simple bind is done to validate credentials. Otherwise the given attribute is compared with the given `principalAttributePassword` using the `SHA` encrypted value of it. DIRECT: Direct Bind - Compute user DN from format string and perform simple bind. This is relevant when no search is required to compute the DN needed for a bind operation. Use cases for this type are: 1) All users are under a single branch in the directory, `e.g. ou=Users,dc=example,dc=org.` 2) The username provided on the CAS login form is part of the DN, e.g. `uid=%s,ou=Users,dc=example,dc=org`. Available values are as follows: `AD`: Active Directory. `AUTHENTICATED`: Authenticated Search. `DIRECT`: Direct Bind. `ANONYMOUS`: Anonymous Search. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`

Prunes connections that have been idle for more than the indicated amount. This settings supports the `java.time.Duration` syntax ^[?]. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.keystore=` Path to the keystore used for SSL connections. Typically contains SSL certificates for the LDAP server. This setting supports the Spring Expression Language. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.keystore-password=` Keystore password. This setting supports the Spring Expression Language. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.keystore-type=` The type of keystore. `PKCS12` or `JKS`. If left blank, defaults to the default keystore type indicated by the underlying Java platform. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.max-pool-size=10` Maximum LDAP connection pool size which the pool can use to grow. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`

A negative/zero value disables paged requests. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.pool-passivator=BIND` You may receive unexpected LDAP failures, when CAS is configured to authenticate using `DIRECT` or `AUTHENTICATED` types and LDAP is locked down to not allow anonymous binds/searches. Every second attempt with a given LDAP connection from the pool would fail if it was on the same connection as a failed login attempt, and the regular connection validator would similarly fail. When a connection is returned back to a pool, it still may contain the principal and credentials from the previous attempt. Before the next bind attempt using that connection, the validator tries to validate the connection again but fails because it’s no longer trying with the configured bind credentials but with whatever user DN was used in the previous step. Given the validation failure, the connection is closed and CAS would deny access by default. Passivators attempt to reconnect to LDAP with the configured bind credentials, effectively resetting the connection to what it should be after each bind request. Furthermore if you are seeing errors in the logs that resemble a 'Operation exception encountered, reopening connection' type of message, this usually is an indication that the connection pool’s validation timeout established and created by CAS is greater than the timeout configured in the LDAP server, or more likely, in the load balancer in front of the LDAP servers. You can adjust the LDAP server session’s timeout for connections, or you can teach CAS to use a validity period that is equal or less than the LDAP server session’s timeout. Accepted values are: `NONE`: No passivation takes place. `BIND`: The default behavior which passivates a connection by performing a bind operation on it. This option requires the availability of bind credentials when establishing connections to LDAP. `org.apereo.cas.configuration.model.core.monitor.LdapSecurityActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.ldap.principal-attribute-password=` If principalAttributePassword is empty then a user simple bind is done to validate credentials otherwise the given attribute is compared with the given principalAttributePassword using the SHA encrypted value of it.

LDAP search filters can point to an external Groovy script to dynamically construct the final filter template.

The script itself may be designed as:

import org.ldaptive.*
import org.springframework.context.*

def run(Object[] args) {
    def filter = (FilterTemplate) args[0]
    def parameters = (Map) args[1]
    def applicationContext = (ApplicationContext) args[2]
    def logger = args[3]

    logger.info("Configuring LDAP filter")
    filter.setFilter("uid=something")
}

The following parameters are passed to the script:

Parameter	Description
`filter`	`FilterTemplate` to be updated by the script and used for the LDAP query.
`parameters`	Map of query parameters which may be used to construct the final filter.
`applicationContext`	Reference to the Spring `ApplicationContext` reference.
`logger`	The object responsible for issuing log messages such as `logger.info(...)`.

The following settings and properties are available from the CAS configuration catalog:

HealthComponent

HealthEndpoint.health()

org.springframework.boot.actuate.health.HealthEndpoint

CAS, being a Spring-Boot application at heart, includes a number of endpoints to help you monitor and manage the server when it’s pushed to production. You can choose to manage and monitor the deployment using HTTP endpoints, referred to as actuators.

In essence, actuator endpoints bring production-ready features to CAS. Monitoring a running CAS instance, gathering metrics, understanding traffic or the state of our database becomes trivial with such endpoints. The main benefit of these endpoints is that we can get production grade tools without having to actually implement these features ourselves. Actuators are mainly used to expose operational information about the running application – health, metrics, etc. These are HTTP endpoints or JMX beans to enable us to interact with it.

Actuator endpoints are presented by CAS in two categories:

Those that are owned and defined by the CAS project.
Those that are owned and defined by third-party projects, frameworks and libraries such as Spring Boot.

Exposed Endpoints

Note that by default the only endpoints exposed over the web are info, status, health and configurationMetadata. Other endpoints need to be explicitly enabled and then exposed over the web in CAS settings in order to allow access.

To enable and expose an actuator endpoint:

management.endpoint.health.enabled=true
management.endpoints.web.exposure.include=health

# Choose the proper security access level...
# cas.monitor.endpoints.endpoint.health.access=PERMIT

The following settings and properties are available from the CAS configuration catalog:


`cas.monitor.endpoints.form-login-enabled=false` Control whether access to endpoints can be controlled via form-based login over the web via a special admin login endpoint. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.endpoint.health.access=DENY` Define the security access level of the endpoint. Available values are as follows: `PERMIT`: Allow open access to the endpoint. `ANONYMOUS`: Allow anonymous access to the endpoint. `DENY`: Block access to the endpoint. `AUTHENTICATED`: Require authenticated access to the endpoint. `ROLE`: Require authenticated access to the endpoint along with a role requirement. `AUTHORITY`: Require authenticated access to the endpoint along with an authority requirement. `IP_ADDRESS`: Require authenticated access to the endpoint using a collection of IP addresses. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`
`cas.monitor.endpoints.endpoint.health.required-authorities=` Required user authorities. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`
`cas.monitor.endpoints.endpoint.health.required-ip-addresses=` Required IP addresses. CIDR ranges are accepted. This settings supports regular expression patterns. ^[?]. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`
`cas.monitor.endpoints.endpoint.health.required-roles=` Required user roles. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`

Endpoints may be mapped to custom arbitrary endpoints. For example, to remap the health endpoint to healthcheck, specify the following settings:

management.endpoints.web.path-mapping.health=healthcheck


`management.endpoint.health.cache.time-to-live=0ms` Maximum time that a response can be cached. `org.springframework.boot.actuate.health.HealthEndpoint.`

`management.endpoint.health.show-details=never` When to show full health details. `org.springframework.boot.actuate.autoconfigure.health.HealthEndpointProperties.`
`management.endpoint.health.status.http-mapping=` Mapping of health statuses to HTTP status codes. By default, registered health statuses map to sensible defaults (for example, UP maps to 200). `org.springframework.boot.actuate.autoconfigure.health.HealthProperties$Status.`
`management.endpoint.health.status.order=DOWNOUT_OF_SERVICEUPUNKNOWN` Comma-separated list of health statuses in order of severity. `org.springframework.boot.actuate.autoconfigure.health.HealthProperties$Status.`

The health endpoint may also be configured to show details via the following conditions:

URL	Description
`never`	Never display details of health monitors.
`always`	Always display details of health monitors.
`when-authorized`	Details are only shown to authorized users. Authorized roles can be configured using `management.endpoint.health.roles`.

The results and details of the health endpoints are produced by a number of health indicator components that may monitor different systems, such as LDAP connection pools, database connections, etc.

management.health.refresh.enabled=true
management.health.vaultHealthIndicator.enabled=true


`spring.security.user.name=user` Default user name. `org.springframework.boot.autoconfigure.security.SecurityProperties$User.`
`spring.security.user.password=` Password for the default user name. `org.springframework.boot.autoconfigure.security.SecurityProperties$User.`
`spring.security.user.roles=` Granted roles for the default user name. `org.springframework.boot.autoconfigure.security.SecurityProperties$User.`

For basic authentication, the default username is casuser. The password may be automatically generated at startup and displayed in CAS logs if it is left undefined in CAS settings. Additional sources may also be defined that would authenticate the request via JAAS, LDAP, JDBC, etc.

Once endpoints are enabled and exposed, the security of all provided endpoints is handled by the Spring Security project. Protection and access to each endpoint is controlled via CAS settings individually such that you may decide a specific security level and method of authentication for each endpoint independently.

If CAS is configured to NOT enforce endpoint security rules, then all endpoints are considered sensitive and require authentication, typically handled via basic authentication with master credentials defined in CAS settings.
If CAS is configured to enforce endpoint security rules, then each endpoint may be tagged with a specific security rule allowing access via authorized IP addresses, basic credentials, roles and attributes, etc.

Defaults

There is a special endpoint named defaults which serves as a shortcut that controls the security of all endpoints, if left undefined in CAS settings.

To enable additional logging, configure the log4j configuration file to add the following levels:

<Logger name="org.pac4j" level="debug" additivity="false">
    <AppenderRef ref="console" />
    <AppenderRef ref="file" />
</Logger>
<Logger name="org.springframework.security" level="debug" additivity="false">
    <AppenderRef ref="console" />
    <AppenderRef ref="file" />
</Logger>

Reports back general health status of the system, produced by various monitors.

HealthComponent

HealthEndpoint.healthForPath(java.lang.String…)

org.springframework.boot.actuate.health.HealthEndpoint

Actuator endpoints are presented by CAS in two categories:

Those that are owned and defined by the CAS project.
Those that are owned and defined by third-party projects, frameworks and libraries such as Spring Boot.

Exposed Endpoints

To enable and expose an actuator endpoint:

management.endpoint.health.enabled=true
management.endpoints.web.exposure.include=health

# Choose the proper security access level...
# cas.monitor.endpoints.endpoint.health.access=PERMIT

The following settings and properties are available from the CAS configuration catalog:


`cas.monitor.endpoints.form-login-enabled=false` Control whether access to endpoints can be controlled via form-based login over the web via a special admin login endpoint. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointsMonitorProperties.`
`cas.monitor.endpoints.endpoint.health.access=DENY` Define the security access level of the endpoint. Available values are as follows: `PERMIT`: Allow open access to the endpoint. `ANONYMOUS`: Allow anonymous access to the endpoint. `DENY`: Block access to the endpoint. `AUTHENTICATED`: Require authenticated access to the endpoint. `ROLE`: Require authenticated access to the endpoint along with a role requirement. `AUTHORITY`: Require authenticated access to the endpoint along with an authority requirement. `IP_ADDRESS`: Require authenticated access to the endpoint using a collection of IP addresses. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`
`cas.monitor.endpoints.endpoint.health.required-authorities=` Required user authorities. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`
`cas.monitor.endpoints.endpoint.health.required-ip-addresses=` Required IP addresses. CIDR ranges are accepted. This settings supports regular expression patterns. ^[?]. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`
`cas.monitor.endpoints.endpoint.health.required-roles=` Required user roles. `org.apereo.cas.configuration.model.core.monitor.ActuatorEndpointProperties.`

Endpoints may be mapped to custom arbitrary endpoints. For example, to remap the health endpoint to healthcheck, specify the following settings:

management.endpoints.web.path-mapping.health=healthcheck
